Abstract
The frequency of use and the effects of mastitis control practices on SCC and milk yield were investigated. A survey of current management practices was combined with DHI production information to determine the relationship between milk yield SCC, management practices, and production and producer characteristics under field conditions. The expected negative relationship between SCC and milk, fat, and protein yield was substantiated. The SCC for an individual cow was a better indicator of milk loss than was a bulk tank SCC. Most recommended mastitis control practices were estimated to be economically beneficial; however, using a sanitizer in the washing solution and having a company change the milking machine inflations were not economical. Questions were raised about the economic efficiency and efficacy of treating all cows as opposed to selected cows at drying off.
